Rotork is the home of the flagship IQ intelligent electric actuator range. The IQ range features legendary innovations including Rotork’s unique double-sealed enclosure, ‘non-intrusive’ infrared commissioning, datalogging and predictive maintenance capabilities. More recent innovations include the advanced display, Bluetooth® communications interface and absolute encoder.

The IQ functionality and reliability is available for valves of virtually every size and description, including multi-turn (rotary), quarter-turn, isolating and modulating, with watertight and hazardous area approvals to all internationally recognised standards.

Electric actuator ranges also include the AWT for simplified control duties, ROM, ROMpak and Q direct drive actuators for small quarter-turn valves.

Rotork actuators are compatible with a wide range of communication and process control systems. Rotork’s own Pakscan™ system offers advanced actuator network control similar to network control from Profibus®, Foundation Fieldbus®, Modbus®, DeviceNet® and HART®.

Electronic actuators with variable speed control. Electronic setting of torque and stroke with function monitoring. Power supply unit with wide range Input.

Actuator applications for demanding control automation tasks in industrial environments with potentially explosive atmospheres.

The Limitorque product range includes actuators that can be controlled from customers’ motor control centers to electronic actuators that can be remotely controlled field devices. More than 1 million Limitorque actuators have been installed around the world, and some have been in operation for more than 50 years. The ruggedness and reliability of Limitorque electric actuators are among the primary reasons that customers continue to select Limitorque products.

Bernards Controls, inventor of the industrial compact quarter turn actuator, brings to its customers valve actuation solutions supported by decades of experience. Through discussions with users over the years, Bernards Controls has identified a demand for electric actuators that are both simple and sturdy. This demand is fulfilled with Bernards Controls’ FIRST BC labelled products. These actuators are well designed to work under moderate environmental & operational conditions. This range has been developed without compromising on quality, applying the unique expertise and feedback that are the cornerstones of Bernards Controls’ reputation. Thus, the FIRST BC label is the guarantee of actuator solutions with a total cost of ownership (TCO) among the lowest in their category, thanks to easy commissioning, proven reliability and a maintenance-free design. The EZ range products meet all criteria set by the FIRST BC label.
